TO ALL WHOM IT MAY CONCERN:

Be it known that I, W SIMONDS, of Hartford, in the county of Hartford,and State of Connecticut, have invented a new and useful Improvement inTelegraph-Wire Insulator; and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a central vertical section of my improved telegraph-wireinsulator.

Figure 2 is a detached view of the cap or insulated portion of'thcdevice.

Similar letters of reference indicate corresponding parts.

This invention relates to an improvement in the construction ofinsulators for telegraph-wires, and consists in forming the glass,flint, or other insulated portion of the device, independent oi' the pcgby which it is connected with the post for supporting the wires, and soarranged, in connection therewith, that rain or the moisture ofcondensation shall not'settle around the base of the insulator andfurnish a medium for the escapo of electricity from the wire to theground.

By my improved arrangement, a dry ring is preserved around the base ofthe insulator, which eifectually prevents the escape of electricity.

A. is a peg, made of wood or iron, for connection with a post or otherxture, for supporting a telegraphwire, the upper cud ot' which, a, isplaced in a vertical position, and fits in the socket of a cap, B, madeof glass, int, or other non-conducting substance, t-o hold it in place.The insulator B is provided with a groove, b, around the knob at theend, for attaching the wire to it in the ordinary way, as shown in iig.2. The base or lower part of the insulator B is formed like the hub of awheel on the peg a, and having a ange or rim, c, projecting from it allaround, and curving dowmvard, so as to hang over and enclose an interiorcup, d, that surrounds and may form a part of the supporting-peg A, whenmade of iron, or may be made separately, as a collar, around it, whenthe peg is made of wood. The inner base of the insulator B has ashoulder, e, around it, which sets low down in the cup d, and has a thinsheet of India rubber or rubber cloth, g, or other flexible,

non-conducting material, lapped around it, like a thimble or hood, to besecured thereon by its own contraction, which rubber cover, g,descendsnearly to the bottom of the cup d.

It will be seen that the inverted lip e of the insulator B projects overthe upper edge of the lip of the cup d, and protects the base of theinsulator from rain or descending moisture, while the lip of the cup dprotects it from lateral or ascending moisture. It will further beprotected by the India-rubber thimble or hood g, so that the space underit, and below the base of the insulator B, will be dry, and make vitsinsulation on the peg A erfect. f P Having described my invention, Iclaim as new, and desire to secure by Letters Patent- The insulator B,having the invcrtedlip c, in combination with the cup d, theIndia-rubber hood g, and the supporting-peg A, constructed and arrangedsubstantially'as described.
